Description

Levenhuk Ra R72 ED Doublet OTA is a convenient optical instrument. This telescope main purpose is astrophotography, but it is also well suited for space visual observation, including the planets of the solar system and a diversity of deep sky objects. It renders a contrasting image, enables observing even dim stars, and provides a good view. While this optical tube is quite compact and lightweight. This is an advantage on long journeys.

This Optical Tube Assembly (OTA) is an apochromatic refractor with extra-low dispersion optics. It suppresses chromatic aberrations, especially secondary and spherochromatism. The objective fully reveals all of the capabilities of the aperture, creates a picture in high resolution, and allows you to view the fine details of astronomical objects. The optical tube mechanics are precisely calibrated and work flawlessly, thereby allowing you to fully concentrate on observations. Due to the 2'' dual-speed Crayford focuser, you can adjust sharpness very smoothly.

The tube body is made of aluminum with a high-quality blackening. The quick-release thumbscrew allows for installing this OTA on most modern mounts. The kit includes a robust aluminum case for stage and transportation.

Please note: Mount, tripod, and optical accessories are not included.

Features:

  • Apochromatic refractor with extra-low dispersion optics
  • Fully multi-coated optics and a wide field of view
  • Well-balanced chromatic distortion and high contrast
  • Dual-speed Crayford focuser for precise sharpness adjustments
  • Great instrument for photographing and observing
  • Compatible with 2'' accessories

The kit includes:

  • Telescope optical tube
  • Cleaning wipe
  • Aluminum case
  • Protective caps
  • User manual and lifetime warranty

Hi! Can I use Meade HD-60 6.5mm eyepiece with this tube (with 2"-1.25" adapter)? I want to observe planets in detail, will produced image quality be good for this purpose? Is it possible to observe deep sky objects with this tube?
Customer service:
Yes, you can use this eyepiece with Levenhuk Ra R72 ED Doublet OTA. This optical tube is more suitable for planetary observations.

Kyle Wyatt (2013.11.26)
Oh boy I can't tell how thrilled I am with this mini telescope! I finally got it! It can do EVERYTHING! It's like.. as different as chalk and cheese as compared to SC and reflectors! Absolutely pure and clear image. chromatic aberrations appear only when the magnification is critical ( it keeps 185x easily)/ I recommend it to everybody. better than this tube can be only the same apochromat but with larger aperture. That's it - no more hideous mirror-lens telescopes!
